hey...my monitor (nec multisync 77f) all of a sudden is giving off a yellow tint...can anyone help?
Have you recently disconnected / reconnected the cable?
A bent pin in the VGA cable can cause this.
Also, you monitor could be going bad or your color settings may have been changed.
How yellow is it?
If it is just a slight yellowish hue then it may be the color temperature setting of your monitor.
Or it could just be that the cable isn't properly in place.. Happened to me, as I had moved the case around a lot, and not fastened the screws as hard as they should... Made my blue desktop turn quite green...
Try reseating your video card, I cannot see any pins getting bent unless you have recently removed the cable. Tap the side of the monitor and see if it changes, move cable up and down at both ends to check for breaks.
